IPC: E03C1/05
Filed: 1968-01-31
Abstract: 1,194,152. Supply fittings for wash basins &c. ROKAL G.m.b.H. 31 Jan., 1968 [22 Feb., 1967], No. 4996/68. Heading A4N. [Also in Divisions B2, F2 and H4] A liquid discharge nozzle, such as for use with a wash basin, comprises a water inlet spigot 11, a discharge duct and orifice 13, 15, respectively, and, disposed concentrically therearound and insulated therefrom by insulators 12, 16, a tube 17, the tube acting as an antenna and being connected by a conductor 18 to a transistorised radio wave transmitter. The supply of water to the spigot 11 is controlled by an electromagnet shut-off valve, not shown, which in turn is controlled by a relay the contact position of which depends on the detuning of the transmitter. Upon the approach of an object, such as a hand to the nozzle, and hence the antenna, the transmitter responds to open the valve which remains in the open state until the object is removed from the nozzle. If the liquid discharge duct 13 is made of metal and conduts heated liquid, a bimetalic strip 14 is provided to compensate for capacity changes caused by the temperature variations.

Title: Protective coatings, metallic pigments therefor, and the method of making same
IPC: B22F9/04
Filed: 1942-04-17
Abstract: 557,010. Coumarone-indene metallic pigment compositions. REYNOLDS METALS CO. April 17, 1942, No. 5138. Convention date, Oct. 4, 1941. [Class 2 (iii)] [Also in Group XVI] Metallic pigments for paints, particularly rust-proof paints, are made by dry stamping metals or alloys of a hardness of 3.0 or less on Moh's scale with a small quantity of aluminium, which prevents welding together of the metal flakes, and adding aluminium flakes to provide leafing quality to the paint. The soft metals may be scrap foils such as tin coated lead foil or aluminium coated zinc foil and are stamped with aluminium comprising 2 per cent. to 5 per cent. of the total weight of metal, the aluminium serving as a lubricant. Additional lubricant such as stearic, palmitic or myristic acid up to 1 per cent. of the total weight of the metal may be added and imparts a polished surface to the flakes. When the flakes are reduced to the proper size aluminium leafing pigment up to 25 per cent. of the total weight of the pigment is added and the whole mixed with a suitable vehicle. During the stamping process, the temperature of the mill is kept below 160‹ F. to reduce the formation of oxides or carbonates which by rendering the pigment too alkaline would destroy its leafing properties. The pH value should be kept below 8 and preferably about 7.2 to 7.4 and this may be assisted by the addition of a small quantity of an acid salt such as aluminium sulphate or acetate. Suitable vehicles for the pigment comprise paracoumarone indene resins with kettle bodied oils or dibutyl phthalate and with cobalt driers. A rust inhibitor such as lead or zinc chromate may be added.

Title: Process for electro-depositing a metal on conducting granules
IPC: C25C1/16
Filed: 1977-02-10
Abstract: 1517134 Electrowinning with helical electrode flow BATTELLE MEMORIAL INSTITUTE 10 Feb 1977 [12 Feb 1976] 05464/77 Heading C7B Metal is deposited on conducting particles which are fed tangentially as a suspension in electrowinning electrolyte into a helical electrolysis chamber 4. The helix (vertical and cylindrical, as shown, but may be a flat spiral) is bounded on its radially inner and outer walls by electrodes, the outer being cathodic, whereby centrifugal forces throw the particles against the cathode throughout their passage. A particle separator e.g. hydrocyclone 8 separates the liquid off for recycling together with small particles which latter may be obtained from a subsequent stage. As shown, an insulating helix 5 separates tubular anode 3 from cathode helical strip 2. Holes 11 allow gases to escape at 12 through the anode. Internal anode cooling and/or an external cooling jacket may be used. A diluting gas may be fed at 13 to reduce explosion risks. Anode 3 may be rotatable so that the scraping action of fixed helix 5 removes unwanted deposits. An electrode separation of 0.8-3 cm for a diameter of 10-50 cm is useful. Metal e.g. Zn, Cn, Ni or Co may be deposited on to particles of itself or e.g. Cn may be deposited on to graphite. The initial particles may be 0.5 mm in diameter.

Abstract: 433,718. Coating welding-electrodes by extrusion machines. JACKSON, J. G., 611, Clarkston Road, Cathcart, Glasgow. Feb. 20, 1934, No. 5562. [Class 87 (ii)] Coated welding-electrodes are manufactured from wire having mounted thereon a plunger member in an apparatus comprising a closed hopper, containing material having flux-like properties, having attached thereto a relatively long tubular die and being fitted with means to force the material under pressure through the die, means exterior to the die being also mounted on the hopper to guide the wire in its travel through the die. The plunger member b is made of wood, paper pulp, &c. and covers one end of the wire electrode a, the other end being guided in a hole in the cover g. The flux material is forced through the die by a plunger d and a wire f may be provided to force the electrode forward. The die tube e is of glass or other smooth material and is at least as long as the electrode so that before the plunger b emerges from the die, another electrode carrying a similar plunger can be inserted in the upper end. The electrode may be formed from a long length of wire to which plungers are attached at intervals, the wire being afterwards cut up. Specification 388,662 is referred to.

IPC: G01B7/06
Filed: 1974-02-07
Abstract: 1455341 Electro-physical measurement - thickness OWENS-ILLINOIS Inc 7 Feb 1974 [8 Feb 1973] 05601/74 Heading G1N The invention relates to a system for measuring the thickness of dielectric articles (e.g. glass jars) using the attenuation of an R.F. field and a compensated reference signal which is updated before each article is measured, as disclosed in Specification 1380349. The output signal from the above system is preferably fed to an adjustable scaling amplifier 36 which is set so that a thickness of e.g. 0.4 millimeter gives a signal of exactly 4 volts, for ease of use. The signal is then fed to a minimum signal storage unit 60 (to hold the minimum signal detected during scanning of the jars) and voltmeter display. As shown in the Fig. the thickness signal from the known MEASURING UNIT 10..28 appears on line 37 and passes over the contacts of calibration relay 40 to the SCALING AMPLIFIER 36 and thence to MINIMUM HOLD CIRCUIT 60 which comprises a capacitor 70 initially charged to e.g. -15 volts, and subsequently discharged by a less negative measuring signal to e.g. -4 volts from amplifier 63. Diode 69 prevents more negative recharging. The signal held in the capacitor 70 is passed by buffer amplifier 65 to the display unit 78 through an UPPER LIMIT circuit 72 set by the bias on diode 84. The HOLD BETWEEN MEASUREMENTS is ensured when switch 94 opens as a jar is removed thereby allowing gate circuit 90 to conduct and apply -15 volts blocking bias on line 111 through diode 112 to amplifier 63 preventing further discharge of capacitor 70. RESET circuit 86 is activated when switch 94 is closed by the next jar causing gate 90 to apply signal on line 117 to a "one-shot" 120 thus pulsing the reset circuit momentarily to recharge capacitor 70 to -15 volts. CALIBRATION switch 42 operates relay 144 to short diode 69 during adjustments and applies the reference voltage from potentiometer 26 in the measuring circuit directly to the scaling amplifier 36.

Title: A honeycomb core fabricating machine
IPC: B21D47/00
Filed: 1964-02-11
Abstract: 1,047,647. Welding by pressure; making honeycomb cores. ROHR CORPORATION. Feb. 11, 1964 [Feb. 26, 1963], No. 5629/64. Headings B3A and B3R. In a honeycomb core welding machine wheeled carriers movable along bars on each side of the core each have a pair of pins insertable into the cells of the core to support the core. The machine welds honeycomb core 14 from a continuous metal ribbon supplied from a corrugating unit to a guide 18, Fig. 2, from which it is drawn as the core 14 is moved lengthwise by indexing fingers 21 which are movable into and out of the cells of the core 14 and are also movable longitudinally of the core to move an unwelded portion of the core under a welding head 10 having twelve electrode wheels. The electrode wheels are reciprocated transversely of the core 14 to effect the weld and co-operate with twelve electrode pins 19 which are insertable into the core cells and internest with and just below the indexing pins 21, the electrode pins 19 being retracted during the indexing movement of the core 14 by the indexing pins. Cores of any length may be built up between stripper bars 23, 24. When the end cells of a layer have been welded, the indexing and electrode pins 21, 19 are retracted, the core is lowered by half a cell height and moved back half a cell length, the pins 19, 21 are reinserted and the guide is moved to the other side of the machine so that the ribbon is doubled back across the core 14. The core is now stepped in the reverse direction after each group of welds has been effected. The core 14 or a plywood former apertured similarly to the core and used to support the core until it is built up to a certain depth is supported on pins 190A, 190B, Fig. 6, on wheeled carriers 304 running on rails 301 supported on stands below the bars 23, 24 and extending sufficiently to support the full length of the core. The pins 190A, 190B are slidably carried in a block 313 pivoted to the carrier 304. The block carries an arm 321, Figs. 7, 11 (not shown), on which is pivoted a transverse member 325 having headed studs 326, 327, the heads of which engage in slots in the ends of the pins 190A, 190B away from the rounded tips 312. The other ends of the studs 326, 327 co-operate with spring arms 333, 334. The weight of the core 14 tends to drag the extended pin downwards. As during movement of the core each carrier 304 passes below the welding station a projection 344 or 345 on the carrier 304 actuates a switch 350, 351 on the machine frame to energize a solenoid which causes a pivoted hammer 353 to push the retracted pin say 190A into a cell and to extract the pin 190B from another cell which is half a cell width lower. When the end of the core has been welded all the pins 190B will have been retracted and retraction of the indexing and electrode pins 21, 19 allows the core to fall the required amount. During the reverse movement of the core the pins 190B are inserted and the pins 190A retracted. If the carriers on each side of the core are aligned, switches 350, 351 are only required on one side.

Abstract: 1,158,356. Making combustible gas. RUHRGAS A.G. 6 Feb., 1968 [7 Feb., 1967], No. 5836/68. Heading C5E. A method of making a gas interchangeable with natural gas comprises subjecting a feed gas containing hydrogen and saturated gaseous and/or evaporated liquid hydrocarbons having an upper boiling point not exceeding 180‹ C. to hydrocracking in the presence of a highly active hydrogenation catalyst at a temperature in the range 200‹ to 470‹ C. and at a space velocity of 500 to 10,000 Nm<SP>3</SP> per cubic metre of catalyst per hour. The relative proportions of hydrogen and hydrocarbon in the feed gas are adjusted so that the ratio pC n H m  to pH 2 <SP>m</SP>/<SP>3</SP>, where pC n H m  and pH 2  are the partial pressures of each hydrocarbon and of hydrogen in the final gas respectively, is greater than the thermodynamic equilibrium constant for all temperatures in the reaction zone. Soot formation is stated not to occur, and the final gas is rich in methane and may contain up to 20% C 2  to C 4  hydrocarbons. Butane and propane contents should be low to facilitate transmission through pipe lines without precipitation of condensate. Five specific examples are described in which the feed gas consists of coke oven gas with butane, liquefied petroleum gas, ethane and naphtha as the added hydrocarbon.

Abstract: 476,406. Coffee apparatus. DAVIS, H. G. Feb. 26, 1937, No. 5864. [Class 129] A coffee maker comprises an outer container 10, an open bottomed inner container 11 and a device 17 for holding the coffee grounds. In operation, water is placed in the container 10 and coffee in the container 17 which is then hooked to the member 16. The coffee grounds are pressed down by a flanged disc 18. As the water becomes hot, the container 11 is lifted so that the coffee grounds are out of contact with the water, but in contact with steam. The bubbling of the water as it boils, causes a striker 23 on the container 11 to give an audible signal. The coffee apparatus is then lifted from the source of heat and placed on the table. As the water cools, the container 11 sinks, bringing the coffee container into the hot water to make the infusion. The buoyancy of the water lifts the container 17 off the hook and it falls on the struts 24 at the bottom of the member 11. If it is desired to reheat the coffee, the steam generated in the container 11 again lifts the coffee grounds clear of the water during boiling.
